Abstract
This paper presents a new method, called Indirect Two-Speed Method (IT SM), for obtaining electrical and shaft torques in an induction motor drive by means of measuring the speeds of bath lumped-inertia elements assigned to a second order model. The measuring is realized by using high-resolution digital tachometers (represented by incremental encode rs), two frequency measurement systems based on the Double-Buffered Me thod, digital filtering of the raw speed data and numerical differenti ation of the filtered speed data.
